Abstract

The utility model relates to a multifunctional ruler. A scale is arranged on the multifunctional ruler and used for measuring. The multifunctional ruler comprises a convex point which is arranged close to one end surface of the multifunctional ruler and a plurality of round holes. When the multifunctional ruler is used for drawing a circle, the convex point can be used as a center of circle for drawing the circle. The round holes are arranged in a straight line in the length direction of the multifunctional ruler. When the circle is drawn, a pen is inserted in one round hole and rotates around the convex point.

Description

Multifunctional ruler

[technical field]

The utility model relates to a kind of multifunctional ruler, especially a kind of chi that can use as compasses.

[background technology]

At present, the chi that people use has the function of measuring, and when needs were measured length or drawn straight line, people just can use chi.And being used for people, single compasses draw various garden.Common compasses are two leg structures, and wherein, an angle is as the center of circle, and another angle rotates around this angle, thereby draws out the arc or the circle of different shape.These two kinds of instruments can only be realized single function, can not use as a kind of function mutually, therefore, certainly will cause the waste of resource, and take bigger space.

[utility model content]

The purpose of this utility model is to provide a kind of multifunctional ruler, and wherein, this multifunctional ruler can be realized the function of chi and the function of compasses simultaneously, and the feature that this multifunctional ruler has is simple in structure, operation side is century-old.

The utility model is to realize by following technical proposals:

A kind of multifunctional ruler provided by the utility model, a side of this multifunctional ruler is provided with scale, is used to measure, wherein, this multifunctional ruler includes: a spur, spur are located at the end near multifunctional ruler, when multifunctional ruler was used for draw circles, spur was as the center of circle of draw circles;

A series of circular holes, circular hole straight line on the dimension of multifunctional ruler is arranged, and when draw circles, pen is inserted in the circular hole, and rotates along spur.

A kind of multifunctional ruler provided by the utility model, wherein, multifunctional ruler also comprises the center of circle part of a flexibility, spur is located at center of circle part, and, when applying external force, center of circle part can be pressed in vertical direction slightly, and can reset when external force disappears.

A kind of multifunctional ruler provided by the utility model wherein, is provided with shrinkage pool at the back of multifunctional ruler with respect to center of circle part place, makes spur to be included in the shrinkage pool, thereby avoids the scuffing of spur to human body skin.

A kind of multifunctional ruler provided by the utility model, wherein, each circular hole of a series of circular holes is provided with its scale to the spur distance, in order to identify the radius size of described draw circles.

[description of drawings]

Fig. 1 is a multifunctional ruler of the present utility model.

Fig. 2 is the profile of the utility model multifunctional ruler.

[specific embodiment]

Understand easily, according to the technical solution of the utility model, under the connotation that does not change utility model, the those skilled in the art that are familiar with this technology of this area can propose numerous embodiments of the present utility model.Therefore, the following specific embodiment and accompanying drawing only are the exemplary illustrations of technical solutions of the utility model, and should not be considered as of the present utility model all or to the qualification of technical solutions of the utility model.

Please refer to Fig. 1, this multifunctional ruler 1 is similar substantially with the profile of common gage.Wherein, a side of this multifunctional ruler indicates scale 11, is used for measuring distance, and another side is available for users to draw straight line.Near an end of chi, being provided with one can slightly press in vertical direction, and the center of circle part 12 of the compasses that partly link to each other with multifunctional ruler.Preferably, this center of circle part 12 adopts transparent materials to make, and have flexible preferably, make the operator can be easily with its pressing gently.And be provided with spur 122 at the rear portion of this center of circle part 12, when draw circles, this spur 122 is as the center of circle of circle.Understand easily,, can identify by other common mode thereon if this center of circle part 12 does not adopt transparent material to make, make the operator can be easily with the home position of 122 pairs of quasiexpectations of spur.The corresponding position at the rear portion of this center of circle part 12 is provided with a recess 13, is used for spur 122 is included in this recess 13, thereby, make this spur 122 outwards not protrude with respect to the rear portion of this multifunctional ruler 1, avoid this spur 122 to scratch operator's skin.Along the length direction of multifunctional ruler 1, with this spur 122 on same straight line, be provided with a series of little circular holes 13, the bottom of circular hole 13 is provided with the length dimension between itself and the spur 122.

When this multifunctional ruler is worked as chi, with common the same use of gage.And when using draw circles as compasses, the operator is placed on the target location with this multifunctional ruler, with spur 122 center of circle that aims at the mark, and presses center of circle part 12 lightly by transparent center of circle part 12 operators, makes the fixed-site of spur 122.Simultaneously, the operator is inserted into pencil or other apparatus in the corresponding circular hole 13 according to the size of draw circles, and around spur 122 rotation pencils and multifunctional ruler, goes abroad thereby draw.

Though above the specific embodiment of the present utility model has been made exemplary detailed description, these explanations should not thought the whole of the utility model protection domain.For the general personnel that this technology is familiar with in this area, the conspicuous modifications and variations that the foregoing description is done are the utility model and comprise.For example the shape with center of circle part 12 should be square or other shape etc.

Adopt structural design of the present utility model, this multifunctional ruler takes up room less, and is simple in structure, easily manufactured, for the operator, can draw the circle of all size easily by this multifunctional ruler.
